Germany-based heating specialist Viessmann has started industrial production of the Vitocal 250-A Pro large heat pump at its Berlin site.
With flow temperatures of up to 70 C, the heat pump is designed for residential, light commercial and communal buildings. The system generates up to 39.5 kW of heating output and has a cooling output of 21.7 kW. It measures 1,900 x 940 x 1,570 mm and weighs 550 kg.
The new product has a coefficient of performance (COP) of 5.6.
Viessmann says the Vitocal 250-A Pro is also one of the quietest of its kind, with 60.9 dB(A) in noise-reduced operation. The company says this means that the outdoor units can also be easily installed in dense development areas or close to a property boundary.
Meanwhile, the Vitocal 250-A Pro indoor unit offers three mixed heating/refrigeration circuits and a seasonal buffer cylinder. Hot water can be generated using a cylinder charging system or with a cylinder charging pump. Viessmann says instead of a domestic hot water (DHW) cylinder, the Vitotrans 353 freshwater station can also be used, which generates DHW using the instantaneous DHW principle. If required, an additional heat generator can be integrated to cover peak loads.
